The invention relates to a method and a device for measuring the degree of bending in a glass sheet. An optical measuring unit (1) is used for emitting an illuminating ray (4) and for receiving a measuring ray (5). The optical components for rays (4, 5) are directed in a manner that the rays cross each other. When a glass sheet surface (20) is located exactly at the crossing point of these two rays, the light reflects from illuminating ray to measuring ray, the latter being monitored by means of electrical measuring elements (3) which also serve as control elements for a manipulating mechanism (2), whereby said optical measuring unit (1) is manipulated up and down in vertical direction. |
